<div>
    Specify the node path used for the check box display content (this format is common to different formats), the root in the file is represented by "//", and the nodes are separated by "/", such as YAML file content:<br/>
    <br/>
    CheckboxParameter:<br/>
    - key: key-1<br/>
      value: value-1<br/>
    - key: key-2<br/>
      value: value-2<br/>
    - key: key-3<br/>
      value: value-3<br/>
    <br/>
    Display node path:<br/>
    //CheckboxParameter/key<br/>
    Value node path:<br/>
    //CheckboxParameter/value<br/>
    Then, there will be three check boxes, of which the display contents of the check boxes are: key-1, key-2, key-3, and the values obtained after checking the check boxes are: value-1, value-2 , Value-3<br/>
